closing arguments, after six weeks of often bizarre testimony, the jury should finally get to decide the fate of casey anthony starting today. debt debate, congress will keep trying to reach a deal on raising the debt limit, but there may be another way to get the job done. and oil spill, thousands of gallons foul the yellowstone river, but just how bad is the environmental damage? captioning funded by cbs good morning, everyone, on this independence day. good to see you. i'm terrell brown in for betty nguyen.

there will be no independence day holiday for jurors or anyone else for that matter at the casey anthony trial for anyone else in floor. there were fireworks yesterday, the judge stopped the trial and had words with casey anthony's trial and others for taking swipes at each other. >> i assume that you are all professionals, so maybe i am misinformed when i think you will follow the law. i'm beginning to see that orders or anything else may not mean a hill of a bean to any of you. >> so the jury will be back in court this morning, and prosecutors will get one last shot at rebutting closing arguments by the defense. karen brown reports. >> reporter: casey anthony's defense spent its final hours in front of the jury trying to convince them there is not enough evidence to convict her of murder. >> the reason you don't have that evidence that they're desperately trying to find is because it's an unprovable case.

>> reporter: in their closing arguments, they tried to discredit the state's charge that the 25-year-old suffocated her 2-year-old daughter with duct tape and chloroform by attacking the state's evidence, and then tried to pinpoint her father saying the child drowned and then tried to cover it up. they were not allowed to bring up allegations that he molested his daughter as an explanation of her bizarre behavior because the judge ruled they've failed to prove it. >> i don't think anybody here can justify her actions, but they do not constitute murder. >> reporter: many of the seven women and five men on the jury appeared tired as the day wore on. they've now been sequestered for six weeks and are finally expected to begin deliberating on monday, but first the prosecution will have their final word with their rebuttal to the defense. prosecutors have already detailed how casey anthony spent the month following caylee's disappearance lying and partying with her new boyfriend.

>> we can only hope that the chloroform was used before the tape was applied so that caylee went peacefully. >> reporter: the prosecution claims anthony killed her daughter because she did not want to be a mom. the defense believes she's an imperfect mother who's wrongly accused. soon the jury will decide. karen brown, cbs news, orlando, florida. politics now, and the battle over the debt ceiling. the senate will be back in session tomorrow trying to hammer out a deal to raise america's borrowing limit by august 2nd, but with republicans and democrats in a stalemate, a completely different option is being discussed. whit johnson has more. >> reporter: three weeks ago when courtney hinton was asked in a cbs news poll how she thought congress should raise the debt ceiling, she along with 69% of respondents said no. now amid fears of a looming crisis, she isn't so sure. >> i think people don't really understand it.

you really have to pay attention to get what it means. >> reporter: what it means according to the bipartisan policy center is come early august, the treasury would only have enough money to pay about 56% of its bills. former treasury official jay powell says the government would likely pay interest first, leaving popular domestic programs in jeopardy. >> it could be social security, it could be medicare. it could be medicaid. we can't pay everything. >> reporter: the stalemate in washington has some asking if president obama can simply bigfoot congress, and order the treasury keep borrowing. there's a little known section in the 14th amendment saying the public debt of the united states shall not be questioned. >> if the congress refuses to act, the argument would run the president of necessity must act in order to follow the command of the constitution. >> reporter: the idea highlights how desperate the debate has gotten. >> it's crazy talk. it's not acceptable for the congress and the president not to do their job.

>> reporter: as the clock ticks down with no sign of progress, americans like courtney hinton can only watch in disbelief. >> this bickering and waiting until the last minute, we're not benefiting from that. >> reporter: as washington returns from the holiday weekend, sources close to the negotiations say a deal has to be reached by july 22nd in order to get it through congress in time. whit johnson, cbs news, the white house. meanwhile three u.s. senators are in afghanistan this morning, john mccain, joe lieberman and lindsey graham, they say they're worried president obama's plan to draw down u.s. troops could help the insurgents. joel brown is in washington on that. happy fourth of july, good morning to you. >> happy independence day to you. they say this is a perception problem. the senators believe too many afghans see president obama's plan for a drawdown see this as a sign the u.s. is quitting on afghanistan. they say that perception is a dangerous one. key senators are raising doubts about president obama's

withdrawal plan for afghanistan. >> it is an unnecessary risk. >> i really do worry this may have undercut the momentum. i hope i'm wrong. >> reporter: in kabul sunday, republican senators john mccain and lindsey graham called the strategy too risky and say it could put both american troops and the plan in jeopardy. the plan calls for pulling out 10,000 troops by the end of this year with another 23,000 gone by the end of next summer. >> i hope that it will work out but it certainly deprives us of the necessary troops that we need for the second fighting season. >> the obama administration is standing by its plan saying successes on the ground especially the killing of osama bin laden have made it possible. >> al qaeda is under more pressure than at any time since 9/11. >> reporter: still this deadly taliban raid on a hotel in kabul last week shows insurgents aren't willing to go quietly. >> if we don't succeed here and

the taliban comes back into power we'll be attacked again. >> reporter: while the debate continues, american troops are carrying on with their mission preparing to hand over security back to the afghan people, the drawdown is set to begin this month. terrell, some initial diplomatic moves have been made to jumpstart peace talks with the taliban but on his trip senator mccain saw no signs whatsoever the taliban is ready to talk peace. >> joel brown in washington for thus morning, thank you so much. overseas, thailand elected its first ever female prime minister by a landslide, comes from a political family, her brother was once prime minister but ousted by a military coup in 2006. the country will go along with the election results. peace activists plan to sail from greece today even though the greek government banned their ships from going to gaza. protests yesterday at the israeli embassy in athens.
